ROLLER-BEARING CENTER-PLATE.

Specification of Letters Patent.

Patented April 21, 1908.

Application filed April '19, 1907. Serial no. 369,061.

To all whomi'it may concern:

Be itknown that I, JOHN G. BARBER, a citizen of the United States, residing at Chicago, in the county of Cook and State of Illinois, have invented certain new and use ful Improvements in Roller-Bearing Center Plates; and I do hereby declare the following to be a full, clear, and exact description of the invention, suchas will enable others skilled in the art to which it appertains to make and use the same.

My invention has for its ob'ect to rovide a simpleand eflicient form 0 roller earing center late.

vTo t is end, my invention consists of the novel devices and combinations of devices hereinafter described and pointed-out in the claims. v The improved center plate herein disclosed v20 was es ecijally designed for use on cars, but

it is, 0 course, capable of general application wherever the corresponding functions are depiredh I h n t e accom an 'n 'drawin s, w ,'c illustrate my inve fiti ii, l ike chara%ters iii dicate like parts throu bout the several views. Referring to the drawings; Figure 1 is a vertical longitudinal section through the entire" center bearing on the line 0: m of'Fig. 2, with some parts removed. Fig. 2 isa bottom lplan view of the upper member of the two caring plates, with some parts broken away and others removed. Fig. 3 is a cross section throughtheentire bearing on the line in x of Fi 2, with some of the rollers removed,- 4 is a lan view of the lower member of 516 two plates detached. Fig. 5 is a detail showing a ortion of the upper plate, illustrated In ig. 2, in bottom or underneath lan View. Fig. 6 is a detail showing in e evation or edge view the same' parts shown 'in Fig. 5; and Fig. 7 is a detail showing the roller gap closure detached in V end elevation.

The numerals 1, 2 and 3 represent,res ecl tively, conical rollers, the lower bearing p ate and the upper bearing plate, which parts 00 operate to afford the center bearing. The lower late 2 is adapted to be secured to the truck olster. The upper late 3 is adapted to be secured to the body olster of the car. The lower plate 2 is provided with a hub4, and the upper plate with a hub 5 which fits over or telescopes with the hub 4 of the lower plate, thus connecting the two plates with eedom for swivelingvmovem'ent, with rewhen the latter are ends of the rollers 1 when in into their pocketed position on the upper plate, one at h the car.

spect to each other, when the parts are in 5 working position. The hub 4 ofthe lower, provided with a central passage 6 "on their rol er bearing or tread surfaces to receive between them the said conical rollers 1. The upper plate 3 is provided with a vertical outer flange 7 with inturned lip or lateral flange 8 ada ted to underlap or underreach the outer or arge ends of the rollers 1, pocketed on-the upper plate. The hub 5 of theupper plate is rovided with a lateral flange 9 vadapte to underlap or underreach the inner or small 7 pocketed position on the upper plate.

' The flange 9 is provided with a removable bridge sectlon or gap closure 10 which, when removed, enables the rollers 1 to be entered atime, until, they are al in place. Theibridge section or gap closure 10 is then secured in its proper-place, to close the gap in the flange 9, and, thereafter, all

position on the upper stated, the rollers 1 will t dled with the upper plate 3. As shown, the closure or bridge'section 10', and the seat for plate. Otherwise the same in the flange 9,-are rabbeted to permit the closure to be inserted by endwise radial movement and be fastened to the main flange 9 by counte sunk set screws or rivets ereafter be hanthe rollers will be locked in their pocketed 11, as best'shown in Figs. 5, 6 and 7. The

lower plate 2 is rovided with buflin flanges -12 of segmenta form, located at t e front and'back of the plate, as best shown in Fig.

4-. vThese flanges 12 cooperate withthe vertical flange 7 of the upper plate, and the interlocking hubs 4 and '5 of the two plates to take the forward and backward thrusts on When the the rollers 1 support the up the lowerplate, with a little c earance below the hub 5 and the vertical flan e 7 of the upper plate. The tread or rol er bearing surface of the lower plate is raised in respect to theoutermpst portions of' the plate, and terminates outward inan abrupt shoulder, below which the flange 7 of the upper plate extends. Hence, the flange 7 not only serves'to take the'end thrusts of the rollers parts are in working position,

er plate from repairs.

--1" and by its part 8 to cooperate with the :lateral flan e 9 of the hub 5 to pocket and lock the rol ers to the upper plate, but serves also as a dust guard to the 'rollers and the roller bearing surfaces of the. two plates. Moreover, in. view of the relative positions of the rollers 1 and the tread surface of the lower plate, the dust, sand or other dirt, which may get onto the rollers or the said tread surfaces, will tend to, work downward and radially outward, under the action of gravity and theeffect of the currents of air, and be thereby removed from the bearing surfaces. from catching and retaining any of this sediment, they are provided with waste holes 13, throu h which the dust will be worked outward y the swivelin motion of the plates or be blown outward y the drafts of air.

The advantage of havin the rollers 1 interlocked to the upper p ate 3, so that after once being pocketed therein they will be handled with the said upper plate, must be obvious. It avoids loss in the handling, shipment or assembling of the parts, at the place where a plied to the cars; and prevents loss of t e rollers, when the cars are derailed, or when the trucks and cars are separated, as is often required for making Moreover, when the car body is jacked up for purposes of repairs, the upper plate'and the rollers, of course, go with the car body and there is no opportunity for dirt to be accumulated thereon. On all prior structures, so far as known to me, other than in the structure shown in my own prior application, hereinafter identified, the rollers remain on the plate, thus affording o portunity for the accumulation of sand an dirt To prevent the buffing flanges 12' rotary motion, an

between the rollers" andou; .the bearing surface of the lower plate.

With the structure herein-disclosed, noth ing of this kind can occur. Finally, it.

should be noted, that the center bearing herein disclosed is simple and cheap to make, and is strong and durable in service. Some of the details can, of course, be varied without departing from the spirit of the invention.

The center plate, herein disclosed and claimed, has some features in common with,

my pending application, S. N. 321,154, filed June 11th, 1906, but has these features embodied in better mechanical form for 0thciency in service and economy in construction.

I What I claim is:

A center bearing comprising u per and lower lates having interlocking lllbS outer flanges, and interposed conical r011 ers supporting the upper from the lower plate with clearance be ow the outer flange of the upper plate, the outer flange of the.

lower plate being provided with dust escape passages, one of which plates has lateral flanges formed integral therewith, which flanges lap the ends of the rollers for locking the rollers to the late with freedom for one of which lateral flanges is provided with a roller entrance gap and gap closure, all substantially as described.

In testimony whereof I affix my signature in presence of two witnesses.
